Some cottontail rabbits in Fort Collins, Colorado, have been drawing attention because they have wart-like growths on their faces that look like horns.

Rumors spread online that rabbits infected with a virus that creates a tentacle-like growth on their faces were "invading" the U.S.

The unsightly bunnies are infected with cottontail rabbit papillomavirus, which can cause growths that resemble warts or tentacles.
